The late Alan Rickman was perhaps most thought of for his villainous roles, but he technically only played two, and Snape, as it turns out, technically wasn’t one of them. (The others were in “Die Hard” and “Robin Hood: Prince of Thieves,” of course.) You could even watch him play very nice — as a ghost, as it were — in 1991’s “Truly, Madly, Deeply,” were it legally available to stream anywhere. (You can, wink wink, find it on YouTube.)

Or you could watch him play hilariously prickly in the sci-fi comedy “Galaxy Quest,” as a fine British thespian mostly known for an old role in a “Star Trek”-like sci-fi show, and particularly for his character’s overwrought catchphrase (which begins, “By Grabthar’s hammer…”). No doubt Rickman suffered through “Galaxy Quest” nerds pestering him with that line, but given how delightful the film is — which finds he and his old castmates aboard an actual space ship, doing battle with actual evil aliens — it might have been worth it.

Aziz Ansari’s “Master of None” spent an entire episode lingering on the clash between immigrant parents and their American-born children, who often forget about their very different heritage. It turns out Ravi Patel — who popped up on a later episode, concerning the limited work for Indian actors — made an entire documentary about that very issue. In “Meet the Patels.” The heartsick, 30-something Patel tries his to find love the old fashioned way, which is to say the way his parents did back in their native country. What follows is very light and crowd-pleasing, but underneath lie copious insights about how first-generation born-Americans try to find a balance between often contradictory cultures.

‘The Overnight’

A square couple (Taylor Schilling and Adam Scott) spends an evening with a swinging couple (Jason Schwartzman and Judith Godreche). You might think you know where this setup will end up: the bohemians will prove creepy and the yuppies will emerge even more assured about their lame lifestyle. But “The Overnight” keeps surprising you — keeps playing with our expectations about how far into the breach of alternative living our buttoned-up pair will go. Its semi-conservative ending rankles, but the trip there is bumpier than it ever needed to be.
